A further object of the invention is to provide a wheeled potato digger in which the potato plow and other mechanism is V61? tically adjustable in the carriage-frame with means arranged adjacent the drivers seat for controlling the elevating movement. of the movable parts.

A still further object of the invention is to provide a wheeled potato digger in which the frame carries stone separators in advance of the potato plow, with a, weed separator arranged above the plow and pivot- .ally-mounting the plow so that the depth of cut may be controlled.

With the above'general objects in view and others that will appearas the nature of theinvention is better understood, the same consists in the novel construction, combination and arrangement of parts to be here1n-' after more fully described and then claimed.

In the accompanying drawings which.

show the preferred embodiment of the present invention and to which reference is had herein by like characters designating corresponding parts throughout the several views :Figure 1 is a side elevational view of my improved wheeled potato digger,'with a portion of the frame broken away. Fig. 2 is a. longitudinal sectional view of the same. Fig. 3 is a vertical cross-sectional view through the forward portion of the carriage frame, better illustrating the stone separator and weeders. Fig. 4 is a horizontal sectional View of the middle portion of the machine, illustrating the manner of guiding mechanism for elevating the plow, etc. Fig. 5 is a plan view of a stone gatherer to be used in lieu of the potato plow.

Briefly described, the invention consists of a wheeled potato digger embodying a Specification of Letters Patent.

diggingmechanism, the frame-being 'conu a nection with the potato plow andthe means for feeding the potatoes to the sorting box.

. Referringmore in detail to the accompanying drawlngs, the reference numeral 10 I designates the main portion of the forward carriage frame connected at its forward end by the usual fifth wheel connection to the front wheels 11, while the rear frame portion 12 is supported-onthe rear. wheels 13, the rear-wheels constituting the driving med1umforthe potato conveying belts.

3, are provide d'with across-bar 14 having The forward frame sections '10 as'shown in Fig.

an opening therein through which extends.

a rackbar 15 connected at its lower end to an inverted U-shape d frame 16. Depending 1 from the upper section of the 'U-shaped frame portion is a hanger 17 carrying at its 7 lower end an, elongated bearing 18 for a shaft 19, the said shaft carrying at its forward end a' disk 20provided'with weeder arms 21. The frame 16 is mounted to move vertically in the guides 22 carried by the sldes of the frame 10, and carries anti-fric-- tionrollers 23 engaging thesaid guides 22. The frame 10 carries depending guide members'24 constituting a guide for the cross-bar v sections 27 provided with shafts 28e r*oud ing upwardly through the cross-bar and the sockets 29 and secured in position by thumb screws 30 engaging the same.

Stoneseparators arecarrie'd bythe;

The mechanism for raising the U-shaped I frame 16in the angle guides'22 consists of a pinion 31enga'ging the rack bar 15 and carried on'one end ofa shaft which carries on its other end a worm wheel 32 in mesh with a worm 33 on the shaft 34, the shaft being rotated by a hand wheel 35 positioned v adjacent the drivers seat 36. By operating the hand wheel 35 the pinion 31 which, is.

driven thereby will elevate the rack bar 15 that carries the U-shaped frame 16.

As shown in Figs. 1 and 2, the frame 16 has rearwardly-extending braces 37 con:

nected to the side frames 38, the side frames carrying anv arm 39 that hasa pivotal eon-' nection with an upright supporting member 41. It is to be understood that when the frame 16 is elevated, the side frames 38 carrying the potato conveying mechanism will move on the pivot point lO'and be ele vated with the said frame.

The side frames 38 extend forwardly as at 41 and carry a transverse shaft 42 on which is pivoted a potato plow 43, the angularity of the plow being controlled by a lever 44 'held in adjusted position in a segment 45.

This arrangement is used to deliver the potatoes to a suitable elevator and separator indicated in general at A mounted at the pinion and worm connection to the hand wheel 35. When the frame 16 is elevated,

the extension arms 26 carrying the cross-bar 25 are alsomoved with the stone separators in the guides 24:, with the side frame sections 38 and '41 carrying the platform belt 48 and feed belt 49, all moving on the pivot 40 of the support 41.. a

In operation, the stone separators 27 being in advance of the plow 43 will clear the surface of the ground and permit the plow to gather the potatoes. The revolving weeder 21 arranged above the plow is adapted to remove the weeds and tops of the potatoes before the same reaches the elevator.

Copies of this patent may be obtained for While the forms of the invention herein shown and described are what are believed to be preferable embodiments thereof, it is nevertheless to be understood that various forms, modifications and arrangement of the parts as shown may be had without departing from the spirit and scope of the invention as claimed.

WVhat I claim as new is 1. In a device of the class described, a wheeled carriage, a frame mounted for vertical movement on said carriage, a tiltable plow mounted at the lower end of said frame, a quadrant mounted on said frame and mov- I able therewith, and lever cooperating with said quadrant and connected to said plow to adjust the same.

In a device of the class described, a wheeled carriage, a frame mounted for vertical movement on said carriage, a tiltable plow mounted at the lower end of said frame, a quadrant mounted on said frame and movable therewith, a rotary weeder ournaled 0n and movable with said frame, said weeder being located above the free end of said plow.

3'. In a device of the class described, a wheeled carriage, a frame vertically movable in said carriage, a weeder journaled in and movable with said frame, means to move the frame, stone separators, and an adjustable connection between the stone separators and the frame whereby to move said separators to and from said weeder.

In testimony whereof I affix my signature in presence of two Witnesses.

ERNEST SILBERBERG.
